JUSTICE E. BLALOCK, OF DALLAS, TEXAS.

CULTIVATOR.

Application filed September 4, 1915.

To all who m it may concern:

lie it known that I, J USTIGE E. BLALOCK, a. citizen of the UnitedStates, residing at Dallas, in the county oi Dallas and State of Texas,have invented certain new and useful. Improvements in Cultivators, ofwhich the following is a specification.

This invention pertains to new and useful improvements in cultivators.

The object of the invention is to provide a cultivator involving novelmechanisms for carrying out various adjustments in an eX- peditiousmanner, some of said adjustments being, )rovision for swinging thewheels and the forward ends of the gangs simultaneously whereby L116gangs immediately track the wheels; provision for adjusting thecultivator to the weight of the driver in 131%, seat whereby the machineis balanced; pro-.

cient. and also one in which the several parts will not be likely to getout of working order.

lVith the above and other objects in view the invention has relation tocertain novel features of construction and operation, an example ofwhich is described in the following specification and illustrated in theaccompanying drawings. wherein Figure 1 is a plan viewof the cultivator,Fig. 2 is a side elevation, one of the wheels being omitted. Fig. 3 is adetail of the axle adjusting means, lis a partial plan view of the gangswinging means.

In the drawings the'numeral 1 designates a. transverse supporting frame,square in cross-section and forming the central supporting elementaround which the greater portion of the structure is built. Side framesextend forward from. the main frame 1 and at right angles thereto, andare indicated by the numeral 2. These frames 2 are connected by braces 3with a tongue 4 which is also connected rigidly, with the frames 2 by across bar 5. A pair of seat bars 6 extend centrally and longitudinallyof the ma chine, carrying a seat 7 at their rear ends 3 and united attheir forward ends, wherebv a longitudinal seat member is formed. Thebars 6 are pivoted to the under side of the frame 1 in a suitable manneras indicated at 8 in Figs? and'lO. The seat 7 being rigidly attached tothe bars 6, it is obvious,

that byswinging the seat. said bars are swung on their pivot-s wherebythe front end portion "of said bars or member is swung laterally in adirection opposite to the seat. A grooved roller 9 is j ournaled on thefront end, of the seat member and engages the under side of 'atrack 10suspended from the tongue 4 and cross bar 5.

iInie'a'ch standard'r21 a vertical drive shaft '31 is1 mounted and hasits: upper: portionexwaneshing with a largerbevelgear'i33 securedtostheYadja-cent: ground'wheel"l9. Just above "the members 22 each:shaft 31 includes auni 1 shaft is supported in theaforkeda. end" of" anupright bracket 35 projecting from a collar 39 on the axle member.joint34c'each' standard with its member 22 may be swung forward orrearward without By reason of the swinging the upper portion of thedrive shaft. vOn the upper end of each drive shaft a miter pinion 36 isfixed and meshes with asimil'arpinion 37 fixed on the end of a couplingsleeve 38 which has telescoping engagement with a relatively fixedcoupling sleeve '40 rotatively mounted in a-bearing bracket" L1extending upward from the frame 1.

i The b'racket 35 is correlated with the member 22 of: each standard 21so that when the axle members 23- are moved longitudinally the saidpartsare carried therewith, and by reason of the telescoping couplingsthe trans mission 0f motion to:the sleeves 40 is not broken. Each sleeve40 is fixed on' shaft unember 12 extending therebetween over the a xle'members." A- pair of miter gear-s43 are loosely confined on the shaftmember at the center thereof and mesh with a miter gear :44disposedk-horizontally thereunder and whichphas driving connection witha bevel ipinion 45 meshingwith the pinion 25. The gear-144E and thepinion 415 are supported by a bracket 46 mounted on the frame 1 as isbest shownin :Fig. 10. A clutchcollar 47 is splined onthe shaft memberbetween the gears 43 and whenthrown either way engages one of the said"gears and revolves the vsamefi These gears rotate the sleeve 24tyonerotating it in one directionand the-other ro-' tating it in the oppositedirectiomwhereby the axle members'23 are extended or retracted.

'r-In order to swing the' ground wheels on theirvvertica-Laxes soas=to:guide the cultividech withi forwardly extending integral arms 48.The outer end of each arm is piv- 'oted to' the outerend of a'link 49which is lwpivotedat its inner' end tothe lower end of "The' 'axle'-members 23 extend through the a main frame 1 concentrically thereof,;said 2: members being supported in" bearings 30" at a vertical lever 501 centrally pivoted on the "lower e'nd "'of an arm 51 projecting down-52. having' itsinner end screw threaded and engaging in a sleeve 53disposed-over the seat bars 6. The sleeve 53 exhibits an angularshapeincrosssection but'is rotatively I confined inxcli-psi54: hanging from"the seat barsas' sh-own best in Fig. 22. "The sleeve "53 being rotatablebut fixedr'against lateral displacement causes'the rods 51 to beextended ortretracted owing' tothe opposite threading o fhthe rods. "Abevel' gear 55 is provided with ianextended huh'SG-and is slida-bleon=the*sleeve 53 which however 'owingrto its. contouris rotated by saidgear. However the hub is fixed against sliding by an angular bar 57extendingtherefrom and embracing the hub of a bevel pinion 58 whichmeshes with the gear 55 and is mounted to be revolved by thev pinion 28on the shaft 29 which is supported in a bearing hanger 59 suspended fromthe frame 1 as is best shown in Fig. 10.

It is obvious that when the axle members are extended or retracted therods 52 must be adjusted likewise and this is accomplished by thepinions 28 and 58 and the gear 55. When it is desired to swing thewheels to either side so as to guide the cultivator the driver byswaying his body swings the seat 7 and the seat bars 6 toward the sidetoward which he desires to swing the wheels. The bars 6 through theclips 54 swing the sleeve 53 which pulls the rods 52 and swings theupper ends of the levers 50 so that their lower ends are swung opposite,whereby the wheels are swung through the agency of the links 49 and arms48. It is desirable to at the same time swing the gangs 12 and this iseffected by links 60 pivoted to the bars 6 and extending laterally underthe frames 2. The outer ends of the links 60 are pivoted to crank member61 rotatable on vertical rods 62 fixed at their upper ends to the frames2 and resting at their lower ends on brackets 66, bent and having theirrear ends secured to the main frame (Fig. 2) and their forward endspivoted to the lower ends of straps 67 hanging from a cross bar 68mounted on the tongue 1. The brackets also support the crank members 61(Fig. 5). The lower ends of the cranks have yokes 63 in opposed relationto the swinging arms of the cranks. Crossed bars 64 and 65 have theirinner ends pivoted to the ends of the yokes, the bar 6-1 being pivotedto the link 15 and the bar 65 to the link 13, whereby the gangs 12 andthe foot frames 17 are swung in unison with the wheels 19 and in theproper direction. The gangs have stirrups 69 for the feet of thedriverwhereby the rear ends may be swung as desired.

forward and the other arm extending up right and carrying a bevel gear71 at its upper end, which gear is fixed on the rear end of a forwardlyextending shaft 72. The gear is disposed between and meshes with similargears 73 which are looselyconfined on the shaft 12. 'Between the gears73 a clutch sleeve 74s is splined on'the shaft 12 and by throwing thesleeve 74 to either side it is engaged with one of the gears 73 andtransmits motion thereto.

The forward end of the shaft 72 is supported in the other arm of thebracket and has fixed thereon a bevel pinion 75 I meshing with a miterpinion 7 6 fixed on the upper end of a vertical shaft 77 also sup portedin the bracket 70. The vertical shaft has a-screw threaded portion onwhich a col lar member 78 is engaged, while the lower end of the shaft77 rests on a supporting bar 79 extending from the frame 1 to the bar 5.The vertical shaft being rotated raises or lowers the member 78according to the direction of rotation. A rearwardly extending lever 80has loose connection with the member 78 and passes through the frame 26so that the side members of the same rest on said lever which is looselyhung on one of the axle members by a strap 81.

In Fig. 13 the parts are in normal position or what may be intermediateposition.

It is obvious that if the shaft 7 7 is rotated to the right (Fig. 1) themember 78 will be moved downward by the screw threads and the lever 80swung downward, whereby the frame 26 will be tilted forward. The

axle members 23 being fastened to the said ,lVhen the machine isproperly adjusted the tongue 41 will be poised. It will be under-- stoodthat all adjustments are made while the cultivator is traveling and thewheels 19 revolving, except those effected by shifting the seat bars 6.

For raising and lowering the gangs 12 duplicate mechanisms are employedand a description of one will suffice for both. A drum 82-is looselyconfined on the shaft 42 and is arranged to wind a steel cable 83thereon. This cable passes rearward and downward at an angle and over aguide pulley 85 journaled in a bracket 86 mounted on a verticallvslotted housing 8 1 through which the cable depends. The cable isattached to av jointed rod 87 which is attached to the gang 12 andpivotally supports the latter. The rod 87 is adapted to enter the slotof the housing when the cable is wound on the drum in raising the gang.and a notch 88 near the upper end of the rod is engaged bv a horizontalspring latch 89 projecting into the slot, whereby the gang is held initselevated position.

The plungers C and F are connectedwith weight" shifting mechanism; while'the plungersD and E are associated with the means for adjusting theaxle members'23.

In Figs; 8 and 9 the controlling mechanism for adjusting the axlemembers 2-3 is shown in detail. I suitably supported 'on' the frame 1incloses said mechanism. The object of this mecha-' nism is to shift theclutch sleeve or collar 17 intothe gears 43. As shown best in Fig. 10 ashifting lever 95 engaging the collar is centrally pivoted on a bracket96 which also supports the casing 94 and into which latter the rear endof the lever projects.

same and causes the return of the lever 95 when the lefthand dog 1061spulled down. For retracting the axle members the operation is reversedby depressing the button of the plunger E, which pullsdown the righthand plunger 97 and permits the lever 95 to be shifted to the rightwhereby the collar 47 is shifted to the left and engaged with the lefthand gear 43.

For controlling the sleeve 74 a shifting lever 113 is centrally pivotedand projects into a casing 114 mounted on the main frame. The lever 113normally stands idle so that the sleeve is intermediate the gears 73 andhas its rear end between a pair of spring pressed beveled plungers 115mounted in the case, said plungers being similar to the plungers 97.Dogs 116 like those 106 are also mounted in the casing. Transversehorizontal levers 118 have connection intermediate their ends (Fig. 19)with vertical rods 117 depending from the plungers 115. These levers arepivoted bell-crank levers 119 similar to the levers 100, said levers 119having their lower ends connected two of thelevers'92 by means of links120. The links 120 are connected with the levers of the plungers C andF. The bell-crank levers 100 and 119 are pivoted on brackets 121depending from a lower deck 122 supported from the main frame and. abovewhich is supported an upperdeck123.

As shown in Figs. 11 and 13 an angular lever 124 has its upperportion'pivoted on a bracket 125 projecting from the frame 1. A flatspring 126 fixed to the upper end of the lever 124 has its upper end inengagement with the shifting lever 113. The lower end of the lever 124is connected by a link 127 which has its lower end pivoted to the rearend of the lever 80, the said rear end being enlarged as shown in Fig.12. As shown in Fig. 11 thelever 124 is tilted and the spring 126 bentso to be under tension and tending to force the shifting lever to theleft. By depressing the. button of plunger C the left hand plunger 115would be pulled down and the shifting lever swung to the left past thedog 116 on that side. The sleeve 7 4 will thus be moved to the right andthe right hand gear 73 thus revolved whereby the collar member 7 8 willbe carried downward as previously described. In Fig. 11 the collar issupposed to be in its upper position on the shaft 77 whereby themachineis tilted rearward for a light weight driver. The button of plunger C isdepressed to shift for a light weight driver. When the sleeve 74 isshifted 'to'the right the member 78 is run upon the shaft77 whereby theframe 26 is tilted rearward. A rod 128 depends from the lower end of theleft hand dog 116 and has a projection on its lower end in the path ofthe enlarged rear end of the lever 80 which strikes said 11201 tion andpulls the rod downward when the lever 80 has been swung to its limit bythe collar reaching its highest point and the adjustment beingcompleted. The pulling down of the dog releases the shifting lever 113which returns to normal position. When the lever 80 is swung as justdescribed the angular lever is swung by the link 127, downward and thespring 126 bent so as to exert its tension to the right, whereby thelever 113 is returned to normal as described. The button F is depressedto shift for a heavy man and causes the right hand plunger115 to bepulled down so thatthe shifting lever is swung to the right and thesleeve 74 to the left. l/Vhen the collar member 78 has been run on theshaft 77 and the rear end of the lever 80 swung upward, the latterengaged a bell-crank lever 130 having its upper end connected to a rodwhich is attached to the right hand dog 116 and pulls the latter downthus permitting the shifting lever to return to normal position.

For releasing the cultivator gangs the plungers B and G are employed andeach operates as follows: A rod 131 is attached to the lower end oflever 92 and has its for ward end attached to a bell-crank lever 132(Fig. 18) which has its other end attached to a rod 133 extendingparallel of the frame 1 and having its opposite end attached to thelatch 89 which is withdrawn when the I ing into a casing 135. Adescription of one.

shifting meanswill sufiice for both as the means are duplicates, onebeing controlled by the plunger A and the other by the plunger H. Fromthe lever 92 a link 137 errtends forward and is pivoted to the lower endof a verticallever 138 pivoted on the lower deck 122 and being pivotedat its upper end'to a bolt 139 which is slidable on the upper deck 123.A rod 140 extending from the casing 135 parallel with the frame 1 and atright angles to the bolt impinges said bolt and is held thereby. hen thelever 92 is I swung by depressing plunger A or 'H the rod 137. (Fig. 2)is pulled rearwardly whereby the lever 138 is swung so as to move bolt139 forward so that an offset; (Fig. 24) therein I is broughtoppositethe end of therod 140 which is sprung into the ofiset. Within the casinga sliding latch bar 143 disposed at right angles to the rod 140 bears onsaid rod at one end and projects into the path of a right-angularshifting member 155 at its other end as shown in FigL14. A lever 144 ispivoted in then casing, and has. twofiat springs145 and 146,the;formerengaging the rod 140 and tending to force it toward the bolt and thelatter engagingthe-bar .143 and;
